Double check my math please.
Double check my math please. I would like it if some one could double check my math, I am building a 402 and want to make sure things are correct.
Bore 4in
Stroke 4in
Head Gasket Diameter 4in
Compressed Head Gasket Thickness .05
Combustion Chamber 61cc
Dished Pistons 8cc
Piston Deck Clearance ABOVE Deck .006
Calculated Engine Compression Ratio 11.55
Also if this is correct can I still run 93 octane?

I come up with 11:55. You should be ok on 93 octane with a spot on tune. A little larger combustion chamber with tighter squish will be less prone to detonation and yield the same compression. Perhaps an .040 gasket with 63cc chambers - will gie you 11.56:1.
